摘要：
The utility model relates to agricultural machinery, in particular, to seeders for sowing grain crops. Combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters. Each coulter contains a rack, lancet paw, seed tube, along the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of the rack in front of the rack, the front face of which is pointed. The stand is hollow and mounted along the longitudinal axis of symmetry of the lancet paw. Between the wings of the lancet paw parallel to the cutting edges of the wings of the lancet paw there is an isosceles triangle plate, the apex of which is directed towards the direction of movement of the lancet paw, and the sides are rigidly fixed to the inner sides of the wings of the paw. A horizontal groove is made at the base of the plate in the shape of an isosceles triangle. The seed tube is installed vertically in the axis of symmetry of the lancet paw above the horizontal groove of the plate, and a vertical groove is made on the back of the lower part of the seed tube, a subsoiler in the form of a tetrahedron is installed on the extension of the vertical axis of symmetry of the rack and coaxially to the direction, with the sharp edge directed towards the direction of movement of the opener. An outlet is made in the lower part of the subsoiler and is directed to the side opposite to the direction of movement of the coulter, and the outlet openings of the vas deferens and the subsoiler are located at a distance equal to the required difference in the depth of seed and fertilizer placement. A follower roller is installed behind the coulters, with the back of the frame of the combined sowing unit, L-shaped brackets with guide bushings are rigidly fixed. Rods are installed in the guide bushings and equipped with springs, a U-shaped frame is installed under the L-shaped brackets, and a packer roller is installed in the U-shaped frame. L-shaped bracke
